Hey guys, I'm having lots of problems with my setup since adding my 3rd 980Ti. Apparently my Antec HCP-1300 1300w PSU can't handle the load. I thought I was having problems with my old HCP-1200 and they upgraded me to the HCP-1300 for free, and it's a POS. It's only rated for 1400w max. The HCP-1200 was rated for 1700w+. I want it back. 😡 I spoke to the tech support at Antec and they suggested I buy a 2nd small PS, use the link function and run it externally. Either that or buy a bigger PS. Nice. Needless to say I'll never buy Antec again. Bastards.
OK, I need a better PS. It needs to be able to handle 3-Way SLI 980Ti on a Haswell 5820k @ 4.3GHz, all GPU's/CPU'ed overclocked/overvolted. With 7 drives+peripherals.
Problem is I'm pretty sure my apartment wiring can't handle a 1500w/1600w PSU or I'd pick up the EVGA 1600w. It probably needs a dedicated line and I don't have one for it.
HCP-1200 ran 3-way 6OG Titans for years+ more. It was awesome. 😢
Are you sure your old PSU was rated for 1700 watts?

And are you definitely sure whatever the hell you're running is too much for the HCP-1300 PSU? Three overclocked 980 Ti cards would draw around 750~800 watts, while the 5820K even overclocked can't be more than about 150~200 watts. Seven drives and the rest of your PC including motherboard and peripherals would likely be no more than 150 watts. Have you made sure to balance what you're connecting to the power cables so you aren't overloading a single rail?
